Don't let pride keep you from considering:
* Without DNA there is no life in this world.
* DNA is one of the most amazingly complex chemicals around. It contains the information necessary to build and reproduce an organism.
* Consider the probability that even if you have all the components of DNA sitting around together, that they would form themselves into DNA. In our bodies, DNA is put together by a complex system of protein "machines". These "machines" are in turn cranked out by our DNA. You can't have one without the other.
